When voice is operating on a mesh network, calls must not traverse more than two hops. Each sector
must be configured to require no more than two hops for voice.
RF considerations for voice networks are as follows:
Coverage hole of 2 to 10 percent
Cell coverage overlap of 15 to 20 percent
Voice needs RSSI and SNR values that are at least 15 dB higher than data requirements
RSSI of -67 dBm for all data rates should be the goal for 11b/g/n and 11a/n
SNR should be 25 dB for the data rate used by client to connect to the AP
Packet error rate (PER) should be configured for a value of one percent or less
Channel with the lowest utilization (CU) must be used
On the 802.11a/n or 802.11b/g/n > Global parameters page, do the following:
Enable dynamic target power control (DTPC).
Disable all data rates less than 11 Mbps.
On the 802.11a/n or 802.11b/g/n > Voice parameters page, do the following:
Load-based CAC must be disabled.
Enable admission control (ACM) for CCXv4 or v5 clients that have WMM enabled. Otherwise,
bandwidth-based CAC does not operate properly.
Set the maximum RF bandwidth to 50 percent.
Set the reserved roaming bandwidth to 6 percent.
Enable traffic stream metrics.
On the 802.11a/n or 802.11b/g/n > EDCA parameters page, you should do the following:
Set the EDCA profile for the interface as voice optimized.
Disable low latency MAC.
On the QoS > Profile page, you should do the following:
Create a voice profile and select 802.1Q as the wired QoS protocol type.
On the WLANs > Edit > QoS page, you should do the following:
Select a QoS of platinum for voice and gold for video on the backhaul.
Select allowed as the WMM policy.
On the WLANs > Edit > QoS page, you should do the following:
Select CCKM for authorization (auth) key management (mgmt) if you want to support fast roaming.
On the x > y page, you should do the following:
